As for the T4 twinscroll, it decreases spool about 3-400rpm or so but the transient response is where it makes a big difference. Part throttle and off boost response is night and day different than singlescroll. The main thing is choosing the correct size turbo housing when going twinscroll.

Have any of you guys had a direct experience with 2.3 and 6466 or know someone with that setup..
